In many ways, economies are like humans and hurricanes. In physics terms, all three aredissipative structures. They need to “dissipate” energy of the right kinds to remain “alive.” All dissipative structures are temporary in nature. No dissipative structure, including an economy, can...
Unmanned/unattended naval undersea sensor systems: examples of today's technologies and challenges for the future The use of sensors for undersea warfare (USW) missions involves a wide spectrum of approaches. Among the many related research and development thrusts is a... D Pistacchio - Internationa...

As advanced sensors and weapons require high power, naval vessels have increasingly adopted electric propulsion systems. This study aims to enhance the efficiency and operability of electric propulsion systems over traditional mechanical propulsion systems by analyzing the operational profiles of modern naval...

Naval vessels, which are subject to explosion risk during the war state, demand more structural safety. One study improved the naval hull with a multi-layer projective structure to withstand blast and fragment/debris loadings [139]. To measure its crashworthiness, dynamic strain gauges were placed...
